Title: INTRACARDIAC DEFIBRILLATION CATHETER SYSTEM
Abstract:
The purpose of the present invention is to provide an intracardiac defibrillation catheter system which can ensure that no voltage is applied to electrodes of a defibrillation catheter during electrocardiogram baseline drift. This catheter system comprises a defibrillation catheter 100, a power supply 700, and an electrocardiograph 800, and the power supply includes a DC power supply unit 71, an external switch 74 that has an energy application preparation switch 744 and an energy application execution switch 745, and an arithmetic processing unit 75 that controls the DC power supply unit. When an abnormal wave height event occurs during the time from input of the energy application preparation switch to input of the energy application execution switch, the arithmetic processing unit controls the DC power supply unit such that a DC voltage is applied to a first DC electrode group 31G and a second DC electrode group 32G in synchronization with an event (Vn) only when the event (Vn) is sensed after a fixed waiting time has elapsed from the occurrence of the abnormal wave height event.
